PCB DESIGN
Using Systems Design Methodology to Manage Complex PCB Designs
Managing the hundreds of interconnections between boards and external connectors and controls, manually, and without error, is virtually impossible. Is there a better way to ensure new configurations communication and design synchronization?

FABRICATION
Cost Comparison of Complex PCB Fabrication using Traditional Sequential Lamination Methods versus Interconnect with Conductive Paste
As feature sizes become smaller, the cost of PCB fabrication goes up. Sequential lamination of complex circuit boards, in particular, is a time-consuming and expensive process. This study analyzes costs associated with traditional methods compared with an alternative that uses conductive paste as interconnect between cores.

FEATURES

INSPECTION
Magnification vs. Resolution in Visual Examination Specifications
Widely used standards are inadequate when it comes to specifying visual inspection in terms of magnification, as the manner in which an optical aid is used impacts its magnification. Resolution is a critical parameter that we recommend specifying, along with magnification in requirements for visual inspection.
